Abstract (en)
1. Unit cylinder head for a reciprocating internal combustion engine with a largely cylindrical outer wall (4), running from the cylinder head bottom (2) to the cover plate (3), and a cover plate (3) being convex towards the cylinder head bottom (2), in which plate a cylindrical valve guide (9) is centrally located, running from this plate to the cylinder head bottom (2) and whose inner space (10) - being open at top - is designed to receive an injector (11), characterized in that at the point where the injector guide (9) crosses the cover plate (3) - above a seal (12) situated between injector (11) and injector guide (9) - there is an annulus (14) formed by the injector (11) and the injector guide (9), from which annulus two radial oil drainage holes (15, 16) branch off to the two side walls (17, 18) of the cylinder head, which holes are sections of an oil collecting line.
